.22 QEV Air Rifle
Just a quick mashup of random unused parts. Basicly it's a 1/2 QEV piloted with a 1/4 blowgun, chamber is 22mm copper and the barrel is 6mm alluminium sleeved inside 15mm copper piping
The shot done was at around 100 psi and i have yet to crank up the pressure.
Unfortunatly there is only a video because photobucket dosen't accept pictures from my camcorder.

The pellets are modified slightly so that the fit the 6mm barrel perfectly.
Velocity? i don't realy know but i'm guessing somewhere in the high 400s low 500s.
Hmmm, 300psi anyone?

Looks good, and yes you need to crank up the pressure 
Given the fact that you're using barracuda heavies, I would say velocity is more likely in the 200-300 fps range.

Who needs a chronograph eh?qwerty wrote:i can tell just by shooting it into the air.
My 14 ft/lbs Air Arms S410 could only do 300 fps tops with heavy pellets, and that's from a 3,000 psi fill...

Not me.... nah but i can see it shoot of into the distance and it's much faster comparing it my cheapo airsoft pistol (200fps with .12g bbs)Who needs a chronograph eh?

And 300 fps? Seriously? TBH thats terrible but i suppose hammer valve guns realease a short burst of air and are designed to shoot lighweight target pellets.
And please don't show me a link of the Airforce Condor...
Just ordered a tin of 13.3g bisley target pellets.

Your 0.12g BBs have a horrible ballistic coefficient compared to heavy pellets, so really what you're seeing is that your pellets *slow down* much quicker than the BBs. If you can see the pellet, it's clearly not moving that fast anywayqwerty wrote:Not me.... nah but i can see it shoot of into the distance and it's much faster comparing it my cheapo airsoft pistol (200fps with .12g bbs)

Fair enough, I could see 0.22" pellets at 550 fps on a sunny day down the scope, but anyway without chrony results this discussion is moot.

How about "I have absolutely no idea what velocity my projectiles are travelling at, and without actual chronograph results any figures I give are pure speculation"

Tell you what - shoot at a soup tin, see what penetration you get. I have the same pellets, we can do a comparative test in terms of penetration, and see how it relates to velocity

Steel soup tin, not aluminium soda can, right?
As soon as I have batteries for my chrony I'll let you know
